The Overhead Beam on the Third Rack
You are operating a stockpicker (order-picking forklift) in a distribution centre with racking that is 9.2 m high. Your machine is a 2019 model with a maximum platform height of 8.0 m and a rated platform capacity of 227 kg, which includes the operator and any tools. The load chart on the machine states that above 6.0 m platform height, the rated capacity falls to 159 kg. You and your harness and lanyard weigh 96 kg combined; you are carrying a 14 kg picking tote. Your supervisor asks you to retrieve a pallet of light bulbs stored on the top beam at 8.0 m, and tells you the pallet weighs 'about 60 kg'. As you raise the platform past 6.5 m, you notice the machine's tilt indicator begins to flash and the mast feels slightly less stable. The floor in that aisle has a visible slope toward a drain. Two other pickers are working in the same aisle.
1. Identify the hazards and explain whether the task can proceed as directed, showing your capacity and stability reasoning.

Hazards include: working at 8.0 m (fall hazard requiring harness and lanyard anchored to the designated point), the de-rated platform capacity above 6.0 m, the sloped floor near the drain, the tilt warning, and other personnel in the aisle.
Capacity check: at 8.0 m the rated capacity is 159 kg. Your combined operator/harness weight is 96 kg plus a 14 kg tote = 110 kg, leaving 49 kg for the load. A 60 kg pallet exceeds the remaining margin, so the load cannot be carried at that height even before stability is considered. The 'about 60 kg' figure is an estimate and must be verified by a load chart or label, not assumed.
The flashing tilt indicator on a sloped floor is a stability warning: the machine must be lowered, moved to level ground, and the slope assessed. Continuing to raise the platform while the tilt alarm is active risks tip-over. The task as directed cannot proceed: the load exceeds the residual capacity, the floor is not level, and the machine is signalling instability. The correct action is to stop, lower the platform, report the slope and tilt fault, and have the load re-assessed or the task replanned (e.g., use a different machine or relocate the pallet).
2. Describe the control measures you would apply, in hierarchy-of-control order, before any retry.

Elimination: remove the need to lift a 60 kg pallet to 8.0 m - relocate the pallet to a lower beam, or use a different machine rated for the height and load.
Substitution: use a machine with a higher rated platform height and capacity, or a different order-picking method (e.g., a reach truck with a suitable attachment) so the operator is not elevated with the load.
Engineering controls: level the aisle or barricade the sloped section; ensure the tilt sensor is calibrated and functioning; fit a load-limiting or load-indicating device; anchor the lanyard to the designated anchor point.
Administrative controls: verify the actual pallet weight, consult the load chart at the specific height, exclude other pickers from the aisle during the lift, brief the team on the de-rating rule, and require a pre-start check of the tilt indicator.
PPE: full-body harness with lanyard, helmet, and high-visibility clothing as the last line of defence. PPE does not correct a capacity or stability problem; it only mitigates the fall consequence.
3. What should you do about the tilt indicator and the slope, and how would you report it?
Read the worked answer
Lower the platform immediately, stop the machine, and do not continue the lift. Move the machine off the sloped section to level ground and re-test the tilt indicator. If the indicator still flashes on level ground, treat it as a fault: tag the machine out of service, remove the key, and report it to the maintenance or fleet controller. Report the slope near the drain as a site hazard so the aisle can be assessed, barricaded, or repaired. Record the incident in the site hazard/incident system, noting the height, load estimate, and the warning observed. Do not resume the task until the slope is controlled and the machine is confirmed serviceable.
